Empress State Building near Earls Court used an unusual Y-shaped design and was completed in 1961. The original intention was to put a hotel on the site. The eventual building was occupied by the Ministry of Defence and GCHQ. GCHQ occupied several floors at the top of the building and vacated this location in 1994. Perhaps as a result of the GCHQ presence, it is often erroneously reported that the Empress State Building was once the headquarters of SIS (MI6). Refurbished in 1997, it is now used largely by the Metropolitan Police and Transport for London.
